About a third of global greenhouse gas emissions come from our food systems, and livestock production is a big part of that. Experts largely agree that one of the biggest actions individuals can take to lower emissions is to eat less meat.But that's a hard sell for a lot of consumers. Americans have actually been eating more meat in recent years, and sales of plant-based meat alternatives have dropped.There are a lot of companies out there trying to innovate climate-friendly meat and alternatives for the future.For our podcast "How We Survive," Marketplace's Amy Scott visits a lab at Columbia University where researchers are figuring out how to make a more convincing and enjoyable fake meat.

Bytes: Week in Review – Wikipedia urges AI companies to pay for its data, again
This week we learned the Japanese investment firm Softbank sold all of its stake in the juggernaut chipmaker Nvidia. We'll get into why on today's “Marketplace Tech Bytes: Week in Review.” Plus, Apple is reportedly pushing back the release of its thinnest iPhone, the Air, and Wikipedia is asking AI companies, once again, to pay for scraping its data.But first, back to that big move by Softbank and its CEO, Masayoshi Son. It cashed out its stake in Nvidia in October, the same month that the chipmaker hit a $5 trillion valuation. The $5.8 billion it netted will be redirected to OpenAI, part of a promised $30 billion to be invested in the maker of ChatGPT.Marketplace’s Meghan McCarty Carino spoke with Anita Ramaswamy, columnist at The Information, about what all this means.SoftBank Sells Its Nvidia Stake for $5.8 Billion to Fund OpenAI Bet - The Wall Street JournalSoftBank sells its entire stake in Nvidia for $5.83 billion - CNBCApple Delays Release of Next iPhone Air Amid Weak Sales - The InformationiPhone Air Sales Are So Bad That Apple's Delaying the Next-Generation Version - MacRumorsWikipedia urges AI companies to use its paid API, and stop scraping - TechCrunchIn the AI era, Wikipedia has never been more valuable - the Wikimedia Foundation

How to train your humanoid robot
Tech firms are racing to develop robot assistants that can take over our dreaded household chores. But teaching machines to perform these deceptively simple tasks is tedious. They need to observe the actions thousands, sometimes millions of times. And there's a cottage industry springing up to provide this training. Marketplace’s Meghan McCarty Carino spoke with Ayanna Howard, roboticist and dean of Ohio State University’s college of engineering, to learn more.

Are there enough workers to build geothermal energy networks?
Combatting climate change will likely require a multi-pronged approach to renewable energy generation. After all, it's not sunny or windy everywhere all the time. Geothermal energy, which harnesses the natural heat generated by the earth, can significantly shrink the carbon footprint of heating and cooling buildings. Those systems are currently just a small part of the HVAC market. But the Department of Energy wants to accelerate production by 10% a year. Rae Solomon at KUNC in Northern Colorado reports on how one geothermal project in the municipality of Hayden is progressing.

The old technique that could power future nuclear reactors
Some AI companies are turning to nuclear power to meet demand for electricity. But traditional nuclear plants can take decades to bring online. Now some tech companies are partnering with startups trying to build small, modular nuclear reactors, designed with speed in mind. One such company, Kairos, has a deal with Google to build a fleet of modular reactors. To do so, it’s relying on a technique first developed in the mid-20th century: molten-salt cooling.
Monday through Friday, Marketplace demystifies the digital economy in less than 10 minutes. We look past the hype and ask tough questions about an industry that's constantly changing.
